Senior Software Engineer - Build and Release

Slack’s Build and Release team makes the build and release of native client software fast and enjoyable for our developers. We maintain the tools and infrastructure that keep our Mac, Linux, iOS, and Android apps (yes, all of them!) building reliably and releasing frequently. We produce reliable, scalable infrastructure and enable the engineering teams building all of these applications to deliver feature after feature with confidence. This team works closely with other teams across the company with the sole mission of making Slack the best place in the world to develop desktop and mobile applications. 

You should have familiarity with most of the target platforms but experience authoring or building software on each one is not expected. Instead, you should be able to research and experiment efficiently, have a bias towards automation, and a desire to make your fellow engineers more productive. 

Slack has a positive, diverse, and supportive culture—we look for people who are curious, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and, above all, collaborative. If this sounds like a good fit for you, why not say hello?
